METHOD OF MAKING CIGAR-WRAPPERS.

Application filed May 23,

Be it known that I, WILLARD J. Goop EL- Low, a citizen of the United States, residing at Bentley Springs, in the county of Balti more and State of Maryland, have invented certain new and useful Improvements in Methods of Making Cigar-Wrappers; and I do hereby declare the following to be a full, clear, and exact description of thedin vention, such as will enable others skille 1n the art to which it appertains to make and use the same.

This invention relates to a method of making cigar wrappers, and has for one of its objects the production of a cigar wrapper from tobacco stems which shall closely resemble in appearance those wrappers made from the blades of tobacco leaves.

The invention comprehends "the formation of a tobacco extract from tobacco stems, the conversion of the stems into a fibrous pulpy mass after the formation of the tobacco extract, andv the formation of the mass into a continuous sheet or web.

The invention also comprehends the treatment of the pulp in a manner to arrange the fiber on the bias in the sheet or web so as to prevent the tearing of the sheet or web 1 n a longitudinal or in a substantially longitudinal direction.

The invention further comprehends the embossing of the sheet or web in a manner to cause the wrappers cut therefrom to closely resemble in appearance those wrappers made from the bladesof tobacco leaves.

The invention still further comprehends the coating of the sheet or web with the tobaccmextract, so that the wrappersmade from the sheet .or web will have the taste and odor of those wrappers made from the blades of tobacco leaves.

In the accompanying drawings:

Figure 1 is a sectional view taken on a vertical plane extending centrally and longitudinally through a machine employed in carrying out my method, and I Fig. 2 is a top plan view of the rear portion of the machine.

l'n carrying out my method, the tobacco stems are treated to'produce a' tobacco-extract. a fter which the stemsf a re converted into afibrous pulpy mass by processes well known to thel'p-aper industry. The "pulp is then run through the machine illustrated in the accompanying drawings. or through any other suitable machine, to convert it into a Specification 01 Letters Patent.

continuous sheet or web which is, during its passage, through the machine, coated by the tobacco extract. The pulp is, before it reaches the pulp vat of the machine, agitated to set up therein divergent currents. The" fibers are, owing to these currents, arranged on the bias in the sheet or web, and in view thereof the sheet or web is prevented from tearing in a longitudinal or substantially longitudinal direction during its passage through the machine. During its formation, the sheet or web is embossed so that wrappers cut therefrom will have the appearance of those wrappers made from the blades of tobacco leaves.

The machine illustrated in the accompanying drawings forms the subject matter of my co-p ending application, filed on the 11th day of A ril, 1919, and serially numbered 289,260. he machine embodies a tank 1 which has its upperside fully open and which is divided up into a large front com-' partment 2 and small rear compartments 3 and 4 by partitions 5 and 6. The partition 5, which has its upper end flush with the upper side of the tank 1, terminates short of the bottom of the tank to provide an opening 7 which establishes communication be tween the compartments 2 and 3. The partition 6, which has its lower end flush with the bottom of the tank 1, terminates short of the upper side of the tank to provide an opening 8 which establishes communication between the upper ends of the compartments 3 and 4. A pulp vat 8 is arranged within the compartment 2. The front wall 9 of the p'ulp vat 8 is spaced from the front wall of the tank 1,'and its upper end terminates short of the upper side of the tank 1 to provide an opening 10 through which the pulp flows into the vat. The lower end of the a front wall 9 of the vat 8 and the bottom wall 11 thereof are curved and spaced from the bottom wall of the tankl. The rear wall 12 of the vat 8 is spaced from the partition 5. The front wall, the bottom and the partition 5 of the tank 1, together with the adjacent walls of the vat 8!, provide a substantially U-shaped compartment about the pulp va't. well known type is journ'aled within the pulp vat 8 eccentrically with'rela'tion to the curved bottom wall 11 and thecurved portion of the front wall 9 of the vat. A couch roll 13 coiiporates with the making cylinder 12".

A making cylinder 12 of any A first felt 14 passes about the couch roll 13 and about guide rollers 15; The top run of this felt passes over a suction box 16 and between a first set of press rollers 17 and 18. The bottom run of this felt passes between sprays 19 and 20, is acted upon bya beater 21, and passes over. a suction box 22.

A second felt 23 passes over the upper press roll 18, over guide rollers 24 and between a second set of press rollers 25 and 26. The bottom run of this felt passes under a suction box 27 which is located in advance of the first set of press rolls 17 and 18.-

An apron 27 passes about heating rolls 28, 29 and30, and about guiding rollers 31. A coating apparatus is located above the heating roll 29, and it embodies a top trough 32, a bottom trough 33, a lower coating roller 34, and an upper coating roller 35. A valved feed pipe 36 discharges into the trough 32, and a plurality of valved nozzles 37 communicating with the trough 32 and discharge onto the upper coating roller 35. \Viping rollers 38 and 39 contact with the coating rollers 34 and 35, respectively. Supporting rollers *40 and 41 are arranged in rear of and in advance of the coating rollers 34 and 35. A spring supported roller 42 is arranged in advance of the heating roll 30 and above the forward upper run of the apron 27. An adjustable reel 43 is slidably and rotatably mounted upon upwardly and rearwardly inclined guides or supports 44 which. are equipped at their lower front ends with stops 45.

A trough 46 is located in the tank 1 in advance of the pulp vat 8, and it is adapt- I ed to catch all pulp discharged from the vat by the rotation of the making cylinder 12*. A rotary suction pump 47 is employed to convey the pulp accumulating in the trough 4.6 to the compartment 4 of the tank 1. A pipe 48 establishes communication between one end of the trough 46 and the intake of the pump 47, and a pipe 49 establishes communication between the compartment 4 and the discharge of the pump. The pump is provided with a shaft 50 upon which is mounted a pulley wheel 51. H l

All moving parts of the machine may be operated by any means, not shownfsuitable for the purpose.

After the tobacco extract has been produced preferably by boiling the stems in water in any vessel, not shown, suitable for the purpose, the stems-and tobacco. extract separated, and the stems converted into a fibrous pulpy mass by any process orig, rocesses known to the paper industry, th-jlpulp is fed into the compartment4of the" tank 1. .The pulp flows from this compartment through the opening '8 into the compartment and it then flows. through the opening 7 into the compartment 2. The pulp thence flows through the opening 10 into the 17 and 18, the secondfelt 23 picks up the l web and carries it under the suction box 27 and between the second set of press rolls 25 and 26. The-web 50 leaves the upper press roll 26, and it is carried by the apron 27 around the heating roll 28. At a point above this heating roll, 'lie web leaves the apron 27 and passes bet een the coating rollers 34 and 35, it being supported on both sides of these rollers by the rollers 40 and 41. After passing between the coating rollers 34 and 35, the web 50 is picked up by the apron 27 and carried around the heating roll 30. The web 50 again leaves the apron 27 at a point above the heating roll 30 and passes over the spring su ported roller 42 and about the reel 43. tact with the front vertical run of the apron 27 by the web 50, and it is rotated by the apron to wind the web-50 about the same.

The tobacco extract is fed to the trough 32 by the pipe 36, and it is fed to the top coating roller 35 by means of the valved nozzles 37 The roller 39 prevents an excessive accumulation'of tobacco extract upon he reel is held incon-.

the coating roller 35, and it discharges the extract removed from the coating roller-35 beyond the side ed es of the web 50 into the lower trough 33. The lower roller 34 picks up the tobacco extract from the trough 33 and applies it to the under side of'the web 50. The roller 38 prevents an excessive accumulation of tobacco extract on the lower coating roller 34, .the extract falling from the roller 38 into the trough 33.

It is to be noted that the web 50 is par-' tially dried before the tobacco extract is ap plied to the sides thereof, that that portion of the apron 27 which picks up the web 50 after it leaves the coating rollers is dried:

into the compartment 2, the pulp is agi- ,tated to set up therein divergent currents.

These currents cause the fibers to be arranged "on the bias inthe web, and in view thereof the fibers prevent the web from tearing in a longitudinal or substantially longitudinal direction during its pass'a e through the machine. The agitator comprises a shaft 52 provided with-a belt pulley 53, and 30 blades or ribs 54. The blades or ribs are ar ranged diametrically opposite each other and are of angular formation with their apices directed outwardly so that they will form a diamond-shaped figure in Which the shaft 52 is diagonally arranged.

What I claim is:

1. The hereindescribed method consisting of producing a tobacco extract from tobacco stems, converting the stems into a fibrous pulpy mass, forming the mass into a sheet, drying the sheet, and impregnating the sheet With'the extract during the drying operation. v

2. The hereindescribed method consisting 15 of producing a tobacco extract from tobacco stems, converting the stems into a fibrous pulpy mass, forming the mass into a sheet, partially drying the sheet impregnating the partially dried sheet with the extract, and 20 thence drying the impregnated sheet.

In testimony whereof I aflix my signature in presence of two Witnesses.
